posed, and'to further provide means for an tomatically unwinding and winding and moving the same from one scroll to the next.

; A further object is to "provide means wherebyboth sides of the scroll may be viewed.

1 A still further object is to produce a device of this character which is mechanically simple, and therefore cheap to manufacture. "Other objects and adVantages-willbe apparent during the course of the following description. T v

Inorder to present reading matter'to the public it has been customary to employ books or cards upon which the matter was printed These methods are both bulky and require a; considerable amount of space. Further a book cannot be successfully used where it is desired tomake a display automatically and where cards are employed the abrasion incident'to the handlingfof the cards results 'in the'same' presenting an unsightly appearance after a short period of fuse.

.I have thereforeprovided inmy invention,

a cylinder within which are mounted aplurality of scrolls in such; a manner that they may be. unwound so as to be exposed to View then rotatedsothat. both sides may be seen,

then rewound, after which the cylinder is moved in such a manner as to present a new scroll which. passes through the same cycle of operation. 7

V In the accompanying {drawings wherein for the purpose of'illustration isshown a preferred embodiment of my invention, the numeral 5 designates' a base, the; numeral 6 a casing mounted upon the base 5'and having roller bearings]? interposed therebetween. Within the casing 6 ispositioned a cylinder 8 having a plurality of shafts 9 extending there-through't'o each ofwhich shafts is securedone end of a webv 11, to

the opposite end of-which web isfattached aweighted bar 12; The cylinder 8 is mounted upon a shaft13 soas to be rotated thereby. By now referring to Figure -I- it will be noted that the 'sha-f,t,,13 has acrank-M attached thereto, the purpose of which is to permit manual turning. of the cylinder 8, when desired. This cylinder is normally adapted to beautomaticallyoperated, and by viewing Figure 2 it will benoted that a gear 16 is positioned upon theshaft 13 and is adapted to be contacted by a worm 17 positioned upon, the motor shaft 18. This gear 17' is normally out ofengagement with thev gear 13v andis only engaged therewith periodically, as Will'belaterdescribed.

V The shaft 18 is rotated by. amotor 19 pivotally, mounted in brackets 21. Upon the opposite end of the shaft 18 is positioned a friction disc 22. The free end-of the shaft 18 is supported between lugs-23 formed upon anofi'set arm. 24 of a lever-26. This lever ispreferablyflformed integral with the main a controllever 27 which is [pivoted upon the arcuate-shaped extremity. 28 of' a stud 29 positioned in the support 81; This-support is best illustrated in Figure V.

- The upper endof the control lever is bifurcated as shownat 32 so as to straddle a collar 33. formedupon asliding sleeve 34.-

This sliding sleeve is provided with oppositely inclined faces 36 and"37.iwhich are adapted to be brought into contact with the friction disc 22 so as to be rotated thereby.

'The'sliding connection between the collar 34 and the shaft 38 is maintained by a key 39. .Theshaft 38 is mounted in the supports I brought into successive engagement with'the female clutch members. 42;;mpupted upon-the shafts 9. The opposite end of the clutch 38 is provided with a head 43. slidable in. .a sleeve 44 within which is positioned a spring 46. The control lever 27' 'ihas formed thereon armatures 47 and 48 which are adapted to be attracted by electro-magnet-s 49 and 51,1'espectively. V

magnet 52 placed at right angles to the electromagnets 49 and 5 1- also acts upon the armatu-res147 and 48-. "*lhese three magnets are electrically connectedvto a common wire 58 which is grounded upon a clockmechanism 54 within which is aplurality of contacts to which the wires 56', 57 and 58 are connected. These wires of course lead to the respective magnets 49;, 52 and 51. The clOckQmechanisnT-54 is also provided with a shaft 59-upon whichis mounted a pulley 61 over which a-bel t 62"p aSses. This beltis inturn reevedover-apuflfley 63-which is fastened to the base-5.

By viewing Figuresl l and itwill be noted that the control lever -27 has an arm 64 extending outwardly therefrom and provided with "a finger-piece 66-.

By viewing Figure 111;, it will be noted that this lever 64jlextends' through the face of the casing G-and jijs adapted to be moved inslots 6 7 and 68 as w-i ll be hereinafter described,

The manner of operatig g my device 'isas follows:

Assuming that the user has a plurality of scrolls which he desires to display, these scrolls may be insertedin the cylinder -8 in any suitable manner, after which the electric switch controlling the motor 19 is turned on, at the sametime the clockmechanism 54 is started the result being-that as the contacts within the clock mechanism make and break their-respective circuits the pulling tension, assuming; that all" of the I 'scrollsare rolled withi-nthe cylinder, should make contact with the contact to the'magnet 51 and will pull the-armature48 toward it, thus movingthe sleeve34 in such a manner as to move 'theinclined face 37 into contact with the friction disc 22: V the shaftto rotate which will transmit motion through the clutch members 41 and 42 to the shaft; 9whichis then positioned at the bottom of the cylinder.-

The resultwill be that the web secured to this shaft will be unreeled and carried downwardly upon it bar 12: As soon as the clock mechanism reaches a point where the current is broken t o-the electromagnet 51 the control lever 27'wi'll return tc its'normal position thus disengaging-the friction disc 22 from its'engagementf with the inclined surface 27'. As soon-as the'elock mechanism This will cause has moved a little further contact will be made so as to deliver current to the electroma-gnet 49. This will move the armature 47 towardit, thus pulling the control lever so as tomove the inclined surface 36 into contact withgthe disc 32. The shaft 9 will now be caused to rotate in a direction opposite to that previously described, which will cause the web 11 to be rewound onto the cylinder.

As soon as the web has been reWou-nd the clock'niechanism will have reached .a point which will break the circuit to the magnet 51 and the rewinding operation will" stop. The clock mechanism will now complete the circuit to the electro-magnet 52 which will rock the control' lever 5,7 in such a manner t-hat'the arm 24 will raise the shaft 1'8 thus bringing-the worm 17 intocontact with-the 1 gear 16; This will result in the'cyl inder 8 being rotated, which rotation will further to a position to be engaged by thegmale clutch member and at this time the clock mechanism will again havebroken. the-'cir 'cuit to the magnet 52, with the resultthat the shaft 18 will again drop to. its normal position and the same cycle will be-repeated V for each scroll. V

If it is desired to read both sides of the scroll the clock mechanism is further provided with a latch mechanism, not shown,

which will intermittently rotate the casing as a whole ahalf revolution, thus exposing first one side to view and then the opposite side. i V V The purpose of the lever 64 and finger f piece 66 is to provide for manually. operating the device ifdesired.

It is of course understood that this device may be employed in stores as a showswindow display or might be employed whereever it is desired to expose readingmatter such as in public places, buildings and the like.

It is to be understood that the form of my invention herewith shown and described is to be taken as a. preferredexample of; the

same and that various changes relativeto the shape, size and arrangement of parts may be resorted'to without departing-from the spirit of the invention orthe scopeof the subjoined claims. V
